The Case-Shiller Home Price Indices are quarterly nominal house price indices for the United States.  The indices are calculated from data on repeat sales of single family homes, an approach developed by economists Karl Case, Robert Shiller and Allan Weiss. The indices are normalized to have a value of 100 in the first quarter of 2000.

A popular and widely used subset of the Case Shiller Index is the 20 Metropolitan Statistical Areas (MSA) view used by Standard and Poors in the S&P/Case Shiller Home Price Index.

The indices are calculated monthly by Fiserv, Inc.- the company that owns and maintains the index and is published with a two month lag on the last Tuesday of every month. Fiserv can provide a deeper view of home prices, at the zip code level beyond the 10 or 20 MSA view used by S&P.

This index family includes 20 regional indices and two composite indices as aggregates of the regions. The MSA indices are three month moving averages. Consequently, so are the composite indices.

The S&P/Case-Shiller U.S. National Home Price Index is a composite of single-family home price indices for the nine U.S. Census divisions, calculated quarterly.
